MAXIMILIAN F. BONZANO, OF PHILADELPHIA, PENNSYLVANIA.

M E TALLIC CROSS-TIE.

SPECIFICATION forming part of Letters Patent No. 437,476, dated September 30, 1890.

Application filed April 10, 1890. Serial No. 347,289. (N0 model.)

To all whom it may con/cern:

Be itknown that I, MAXIMILIAN F. BoNZANo, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Metallic Cross-Ties, of which the following is aspeciiication.

One object of my invention is to so construct a metallic cross-tie that it can be readily and cheaply made from ordinary forms of channel-bars and will effectually retain the ballast, and thus prevent displacement of the tie in any direction, and in connection therewith I provide simple and efficient means for securing the rails to thetie. These objects I attain in the following manner, reference being had to the accompanying drawings, in which- Figure lis a longitudinal section of my improved metallic cross-tie. Fig. 2 is a plan view of the same. Fig. 3 is a view, partly in end elevation and partly in transverse section, showing a rail and a series of ties; and Figs. 4 to 6 are views illustrating modifications of the parts of the invention.

The tie shown in Figs. 1, 2, and 3 is composed of an ordinary form of U -shaped channel-bar A, in which at each end and at the central portionareformed longitudinal incisions or slit-s adjacent to each edge or angle of the bar, the central portion of thc bar being also cut away, so that a series of tongues b and d are formed, the tongues b being at the ends of the tie and the fingers d on opposite sides of the central portion of the tie.

The tongues b and d are bent downward at any desired angle, as shown by full or dotted lines in Fig. 1, so as to form on the tie railsnpporting boxes A', closed at the top for the support of the rails, but open at the bottom, so that when the tie is deposited upon the ballast and the latter is packed into each of these rail`supportin g boxes sliding movement of the tie in any direction upon the road-bed is rendered practically impossible while the central portion of the tie is open. Hence no opportunity is afforded for a central support of the tie upon the ballast, and longitudinal rocking of the tie is thereby eifectually obviated.

The rails B rest upon the flat tops of the boxes A formed by the tie, and are clamped thereto by plates f-one for each side of the rail-these plates overlapping the flanges of the rail and being confined by nuts upon the upturned ends of the U-shaped bolt g, which bears upon a saddle h, inserted between the` looped portion of the bolt and the under side of the tie beneath the rail.

In carrying out my invention various shapes of channel-bars may be employed. For instance, a fianged bar, such as shown in Fig. 4, may be used; or the sides of the bar Inay be flared, as shown in Fig. 5, and in many cases the top of the bar may be grooved or corrugated to increase the rigidity of the tie, as shown, for instance, by dotted lines in Fig. 1l. The U-bolt may, if desired, be arranged diagonally, as shown in Fig. (i.

The formation of downwardly-bent tongues atboth ends of the boxes A may be dispensed' with in some cases and such tongues formed only at the outer ends of the boxes, the use of the tongue at both ends of each box being, however, preferred in all cases.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. The within-described metallic cross-tie, consisting of a channel bar or beam having projecting tongues extending downwardv between the side webs of the tie, so as to form open-bottomed ballast-receiving boxes with flat top bearings for the support of the rails, substantially as specified.

2. The within-described Inetallic cross-tie,

consisting of a channel bar or beam having at the central and end portions of the tie downwardly-projecting tongues between the side webs of the tie, so as to form open-bottomed ballast-receiving boxes having closed ends and iiat top bearings for the rails, sub` stantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
